Density pack of the material

With this pack, you can build a complete investigative approach from observing materials to measuring density. The student observes and compares natural materials such as rocks and manufactured materials such as machined cylinders. Then, they proceed with density measurement in 3 steps: - Measuring the volume of the object by immersing it in the graduated cylinder using a pipette, - Measuring the mass with a balance, - Calculating the density ρ = m / v.

- 1 set of 5 cylinders of equal masses, - 1 set of 5 cylinders of equal volume, - 5 graduated beaker tubes of 250 ml, - 5 rock packets, - 5 sets of 5 calibrated rocks.
